IPC: H04Q3/00
Filed: 1990-08-29
Abstract: VIRTUAL PRIVATE LINE SERVICE Abstract This invention relates to a method and apparatus for providing point-to-point private line service by providing a switched communication circuit only whenever either terminal of the private line service lifts its receiver. In a departure from the prior art, and in order to ensure that no other stations can get access to the private line terminals, the service is provided by assigning both terminals to acommon software defined network, and by routing the call through the software defined network using a non-dialable routing number derived from the identity of a calling station. Whenever either terminal lifts its receiver, a connection is set up within the software defined network; this prevents callers from outside the software defined network from accessing either terminal. alternatively, an ingress switch of a public switched network can directly provide a non-dialable routing number for routing a call from a station that has gone off-hook to a predetermined destination identified in such a way that it cannot be reached by dialing a call. Advantageously, fully private line service is provided without requiring dedicated facilities.

Title: Cooling liquids
Inventor: BRIDDEN TERENCE E
IPC: F28C3/08
Filed: 1990-10-15
Abstract: Liquid is cooled in a columnar vessel 2 having an inlet 4 and an outlet 6 for the liquid. The cooling is effected by introducing liquid cryogen into the vessel 2 through a pipe 14. The liquid cryogen vaporises and crates turbulence in the liquid in the vessel 2. Perforated plates 12 dampen the turbulence and disengage the vaporised cryogen from the liquid being cooled. Pressurised gas is introduced from an inlet 16 into the liquid beneath the liquid cryogen. This pressurised gas crates turbulence in the region where the cryogen enters the liquid and thus is able to prevent local freezing of the liquid in the mouth of the pipe 14. The liquid is typically water and the liquid cryogen typically liquid nitrogen.

Title: Method for making microporous marking structures
Inventor: MCCOWAN JAMES A
IPC: B65D75/26
Filed: 1990-10-26
Abstract: ABSTRACT      A premix capable of forming a microporous marking structure is prepared by kneading a pouch containing the premix, then opening the pouch and removing the premix therefrom.  The mixed premix is then typically poured in a mold, and an absorbent backing layer is placed on the premix.  The premix is then heated to form a microporous structure, and then cooled.  The dispensing package used in this method is a thin-walled, flexible pouch which contains the premix. This dispensing pouch can eliminate the need to make up a batch of premix immediately prior to casting, together with the need to measure the amount of premix needed for each casting.

Abstract: An improved heat sensitive cut-off for blocking the flow through a gas conduit or the like of the type comprising first and second cut-off members disposed in the conduit which co-operate to block flow through the conduit when they are brought together.  The first cut-off member has a socket therein.  A spring biases the cut-off members together,  and a spacer between the cut-off members for separates them to permit flow through the conduit.  The spacer has a portion penetrating partway into the socket in the first cut-off member.  A plug of a relatively low melting point material is located in the bottom of the socket  for  temporarily  preventing  the  spacer  from penetrating further into the socket.  The socket and the spacer are configured so that when the plug melts the spacer can penetrate further into the socket sufficiently that the spring can move the cut-off members together to block the flow through the conduit.  The first cut-off member and the spacer are secured together mechanically or with an adhesive to prevent them from separating and interfering with the proper operation of the cut-off.

Filed: 1991-04-23
Abstract: Abstract of the Disclosure An ignition system for an internal combustion engine, such as an outboard marine engine, which includes an  advanced  timing  schedule,  a  non-advanced  timing schedule,  and a circuit for switching between the two schedules or disabling both schedules based upon engine operating conditions.   The ignition system includes an opto-electronic time base generator which produces two sets of timing pulses relative to crankshaft position which are non-advanced timing pulses and advanced timing pulses.  The time base generator comprises two LED-phototransistor pairs and an encoder disk attached to the crankshaft with slots to  interrupt  the  radiation  path  between  each  LED-phototransistor pair.  The encoder disk is provided with a synchronizing slot, multiple timing slots associated with the cylinders of the engine, and an direction slot.  The direction of the rotation of the engine can be sensed by the spatial relationship between the synchronizing slot and the direction slot.  The non-advanced pulses are generated based upon the trailing edge of each timing slot while the advanced pulses are generated based up the leading edge, wherein the width of the timing slots indicate the degree of advancement of the advanced schedule over the non-advanced schedule.  Both schedules are inhibited based on predetermined operating parameters of the engine or the detection of a reverse engine operation.
